Answer:
<u>width = 126 ft</u>
Step-by-step explanation:
I'm going to assume that I am solving for width.
Area = width x length
84 = 2/3 x width
Now divide 84 by 2/3 to get the width (when you divide by a fraction, you actually multiply by its reciprocal, so it is 84 times 3/2)
84 x 3/2 = width
width = 126 feet
First multiply the parenthesis:
20 - b = 1/3b + 16/3
Then combine like terms:
20 -b + b = 1/3b + b + 16/3
20 - 16/3 = 1/3b + b + 16/3 -16/3
20 - 16/3 = 1/3b + b
44/3 = 4/3b
and if your looking for b;
44/3 (divided by) 4/3 = b
11 = b...is your final answer!
hope it helped :)
Answer:
$306
Step-by-step explanation:
First you make it into fractions. 1/300 = 2/100
The 2 in the fraction represents the tax rate over 100
The 300 represents the microscope price.
Now multiply the 300 and 2 and 1 and 100
300 x 2 & 1 x 100
600 & 100
Now divide these two
Now you have 6
The 6 is the tax
So now add 300 + 6
$306
Let's look at the formula for the volume of a sphere:
Volume = (4/3) (pi) (radius)³ .
If you multiply the radius of a sphere by 'anything',
then the volume gets multiplied by (anything)³ .
Going the other direction, if you multiply the volume by
'something', then the radius gets multiplied by ∛(something).
In this question, the ratio of the volumes is 3 .
So the ratio of the radii (radiuses) is ∛3 = about 1.442 (rounded)
